A linear motor suitable for positioning with a movement distance of several tens of millimeters has been developed for high-speed movement and ultra-precise positioning. The power amplifier section uses a linear amplifier.
- Since there is no accumulation in the normal deviation counter, the command pulse and the encoder pulse (tracking) match, and there is no phase delay between the command pattern and the tracking pattern. (Phase-Locked Loop) - The correlation between the two-axis driver can be traced accurately. - It demonstrates responsiveness even to minute delays. - Since it does not perform sampling control, it has a very high-speed response. - With a maximum of 4 MPPS and high speed, it can accommodate high-resolution encoders. - There is no switching noise.

Applications/Examples of results
Linear motors, spindles, servo track writers, galvanometer mirrors, and others. In particular, they are optimal for ultra-precision machines that require high-speed positioning (a few milliseconds) with minimal feed, as well as positioning using high-resolution linear scales of 0.01μm, and synchronizing position and speed for processing.
Company information
1. Positioning in nanometer units and ultra-precise speed control (PLL) using linear motors. 2. Development of a (real-time) encoder multiplier for achieving ultra-precise control, and a high-speed response servo driver supported by a linear amplifier. 3. Circuit design (including software) and PCB pattern design (CAD) are handled in-house, allowing for short delivery times even for OEM specifications.
